- 摘要：
- <p>The lead-through (1) comprises a first inner pipe (6) forming a conduit for the gas/air and a second outer pipe (5) extending around at least part of the first pipe and having a bottom end for securing to or inside a roof. The two pipes include interlocking first and second support parts with cooperating support surfaces oriented in the pipe length direction. At least one support part has several support surfaces which are spaced apart in the pipe length direction and can be selectively engaged with one or more support surfaces in the other support part.</p>
